Default AUDI A7 Multiple warning lights

Hello everyone, I bought an Audi A7 2014 (not facelift) with 3.0TDI, 150KW S-tronic. Car has 190.000km and is in mint shape. But it has some electrical issues. On start it pops check engine, airbag, and then red warning for ACC, brakes and steering. Car drives perfectly. Only thing thats not working is multimedia display, it comes out of the dashboard, without image and goes back in. I visited many electrics and mechanics but no one has idea for solution. Did anyone had anything similar?

Multiple warning lights tend to be a sign of a dying battery.

As for the MMI, are you getting sound out of the stereo and just the black screen? There are 2 small wires that power the screen that can easily break and make the screen go black. Read up on MMI black screen of death.

My first check was on battery, and yes it was original one from the factory. So replaced that, drove the car and then tried to clear errors on diagnostics but it did not help. Also did check on that two wires because found on the internet that it is common issue, but everything is fine. Also found out that in some occasions screens turns on and it is fully fuctional. Electrician guided me that it could be instrument cluster making short circuit or something causing all these issues, because in some interval RPM gauge just goes to 0 rpm for a second and then comes back normal. So I ordered new instrument cluster, only thing bothering mi that my part number is 4G8 920 933 B and I only found 4G8 920 933 Q and 4G8 920 933 F. We are guessing it will fit with just some coding. We will see..
